GAS-PRODUCER Application filed March 21,

T whom it wring concern:

Be it known that I, Tm'mus B. BENNER, a citizen of the United States residing at Cortland, in the county of Cortland and -State of New York, ha\e invented a new and useful Gas-Producer, of which the following is a specification.

,The present invention relates to improvements in gas producers, and more particularly to that type of gas producer used 'for making illuminating gas in which retorts are heated containing the fuel, the par ticular gas producer herein set forth being designed for obtaining gastrom bituminous coal or slack one ob ect of the present invention being the provision of superposed communicating retr-rts wherein a plurality are filled from a single filling opening at the top of the producerdthus facilitating the filling of the retorts and rendering such operation more simple A further object'of the invention is the provision of a plurality of superposed retorts having centrally disposed inlets alined so that the fuel is delivered from and through the top retort to the bottomretort, there being' neans disposed at the end of each retort for preventing the backing of the fuel against'thc removable ends and at the same time constituting a gas directing'means for permitting the gas generated in the respective retorts to be properly delivered to the final directing and cleaning means.

\Vith the-foregoing and other objects in .view which will appear as the descrip tion proceeds, the invention residesin the combination and arrangement of partsand in the details of construction hereinafter described and claimed, it being understood that changes in the precise einlmdiment of the invention herein disclosed can be made withinthe scope of what is claimed without departing from the spirit of the invention.

In thedrawings-Figure l is a vertical central sectional view through a complete gas producer embodying the present invention, such section being taken on line 1-1 of Fig. 2. Fig. 2 is a cross section taken approximately on line 2-2 of Fig. ,1. Figs. 3 and 4 are detail views illustrating the closures of the retorts.

Referring to the drawings the numeral 1 designates the casing of the producer 55 which is preferably made of brick, the usual Specification of Letters-Patent.

form of generator 2 being provided therein having a plurality of waste gas and line directing outlets 3 outletting to the upper part of the retort containing compartment of the producer. Air is led from the bettom at the opening 5 and -follows the direction of the arrows combining at the port 6 with the gas from the generator 2 to combine therewith and properly heat the space. containing the retort's, such gas following the line of the arrows and outletting at one side at 7 and at the opposite side at ,8, the line 5) being the fiualoutlet .for the waste gas at the left side of the. apparatus, as shown in Fig. 2. r Disposed between the cross walls 10 and 11 in the retort carrying portion of the pro ducer, are a plurality of retolfts 12, ha rving the centrally disposed fuel charging inlets- 13 which are in communicationat-a similar point with thesuperposed retorts 14,:sa-id retorts 14- being disposed between the-partition 1 land the crown partitions 15 0f the retort chamber. Each retort 14 is provided with the charging inlet-l6, which isdisg0 pr-sed above and coaxial with the'correspending-charging ports 13 ofntherctorts 12. Thus when the fuel is directed through the inlet 17' sealed by the gastight closure 18, from the charging car C, nndop'erztted 35 by a poker through the poke holes "2-1, the same will assume the lines as indicated in Fig. 1 the lower retort 12 being the one primarily charged.

In order to properly' seal the outer ends 90. 19 of the respective retcrts l2 and 1a, such outer ends 19 are projected beyond the brick work of the producer and are Sealed' by the covers 20, each cover being provided with the closure controlled poke hole 21 so that the upper level of the fuel may he. maintained by the introduction of s oke; therethrough. Connected to "and ing inwardly from the inner "faoelpf f 'thdf respective closures 20, is an arm ,orgarms 10C .22, which carry the partition on plate 23,

the inner face of which.is lined with fire brick or the like such member 23 providing a channel between its face and the closure 20 for the passage of the gas from the re- 10!: spective retorts. By this arrangement it will be seen that the gas will not be forced to follow a circuitous route which is the usual custom in producers'of this character, but will pass into the respective ends of 1H the retorts 12 an'd'l l, that leading from the 1 being provided with a main charging port respective ends of the retort lz-entering the short couplings 24-24 passing into the space between the plates 23 and-the covers 2-0 of the retort 14 and finally into the couplings 25-25 into the lead pipes or conduits 26.

Thus with this construction, the gas has a shorter distance to travel being led from both ends of the retort and thus prevents the formation of lamp black and carbon, the gas retaining the light hydro-carbon matter in suspense to remain in the gas and there by prevent the formation of naphthalene and free carbon that usually deposited in the tar and the pipes through which the hot gas passes to the respective hydraulic mains 28-28 into which the directing terminals 2727 are disposed and placed in communioation. The pipes 24-24 and 2525 are connected by expansion joints, so as to remain tight at all times and yet permit the necessary contraction and expansion due to the heat.

With this structure of retort and the arrangement ofthe superposed retorts, it will be noted that it ispossible to charge them solid and thus contain a larger charge of coal than is usually the practice, the larger charge of coal preventing the rising gas vapor from the coal to come in contact with any open space or heated walls of the re torts, which tend to remove the valuable hydrocarbonsand deposits therefrom and cause the formation of carbon as an obstruction to reduce the capacity of the retort. The present retorts are so designed and charged in the center, as to prevent the carbon from forming as the lines of admitting air when the retorts are discharged passes along the walls of the retorts and escapes through the charging hole. In this process of manufacture, the gas as deliv ered from the coal is not heldfunder pressure or over the heated retort walls, but is delivered at a shorter distance and at nor mal atmospheric pressure. The resulting by-products thus produce a better and more solid coke, and the tar is free from the lamp black, which thus increases the yield of gas and ammonia liquor.

In operating the-present producer, and in charging theretorts, the same are charged from the center, the lower retort being filled first, the coal being leveled through the respective poke holes 21. The closures at the proper time being removed and the coke discharged by a pusher intoa cooling systeniand in'transit as it is crushed, screened and formed in sizes for use.
